Answer:
A, b,e
Step-by-step explanation:
a: x+6=5+x
+x-x=5-6
0=1
so this eqn is out
b: -2 (x-3)=-2x+6
-2x-6=-2x+6
-2x+2x=+6+6
0 = 12
so this eqn is also out
c:4-4x=3 x+2
-4x-3x=+2-4
-7x=2
×=2/-7
so this eqn is correct ♥
D:4 (x+1)=3 (x+2)
4x+4=3x+6
4x-3x=+6-4
1x=+2
x=2
so this eqn is correct♥
E:5-3x=-3x+4
-3x+3x=+4-5
0=-1
so this eqn is out
c:
